“Yet the company has failed miserably in their duty of care and support towards James Crabtree.

“Instead of protecting him, the company has dismissed him in the most blatant travesty of workplace justice – siding instead with a known troublemaker who is the kind of menace who should be barred from our railways

“RMT is clear that the trumped-up allegations levelled against James are unfounded and that the harsh decision taken by London Midland is not only intimidating but highly offensive towards a hardworking, loyal member of staff.

“RMT has therefore informed the company that a dispute situation now exists between our two organisations and that RMT demand the immediate reinstatement of James Crabtree.”

Officials say they are available for talks, but warn the union will not tolerate allowing rail staff to become “fair game for abuse and intimidation.”
